S50, atomization, pours alloy mixed liquor into bottom pour ladle, bottom pour ladle aperture is at 3.5~5.0mm, liquid stream flows into atomizing cup by bottom pour ladle hole, adopts air compressor machine generation high-speed gas to carry out fragmentation to mixed liquor liquid stream and forms drop, and the mixed liquor drop after fragmentation condenses and becomes spherical powder particle in dropping process;
S60, screening, carries out sieve classification by cooled spherical powder with bushing screen and can obtain unleaded antifriction anticorrosion alloy dusty material.
2. the preparation method of unleaded antifriction anticorrosion alloy dusty material according to claim 1, is characterized in that, in S20, in the time that generation composition Si, A1 go beyond the scope, carries out oxygen blast slag making, makes the Si of super scope and A1 produce respectively silica and aluminium oxide.
3. the preparation method of unleaded antifriction anticorrosion alloy dusty material according to claim 1 and 2, is characterized in that, further, in S50, pour aluminium alloy into bottom pour ladle specific as follows, keep at any time the liquid level of tundish, and cover charcoal, anti-oxidation, before atomization finishes, tundish feed liquid top layer application glass deslagging, in the time that centre is surrounded by 1/3 feed liquid, stop atomization, feed liquid is toppled over, enter next melting, prevented that slag inclusion thing from entering atomized powder.
4. the preparation method of unleaded antifriction anticorrosion alloy dusty material according to claim 1 and 2, is characterized in that, in S50, nozzle bore is 2.0~4.0mm, and nozzle hole number is 6~14, and nozzle angle is 8~20 degree, air compressor machine pressure 0.6~1.3MPa.
5. the preparation method of unleaded antifriction anticorrosion alloy dusty material according to claim 1, is characterized in that, in described atomizing cup, Heat preservation height is 3~10 meters.
